post 3 Perceptual Research ( in place of sona)

ADHD known as attention hyperactivity disorder affects
nearly 3.5 million school age children in the us more commonly in males than
females. When people are affected with ADHD they are less able to recognize
appropriate social behavior, easily distracted or failing to pay attention. It
is hard to detect ADHD consistently usually a physician can observe
behaviors. ADHD is not clear cut but
doctors and physicians have studied and realized that certain receptors in the
brain normally respond to the neurotransmitter called dopamine are not working
properly. Which means that the dopamine is not being produced at normal levels
in the brain, recent work in adult’s points to
a defect in an enzyme called dopa decarboxylase which helps make dopamine. This
defect in dopamine production occurs in the anterior frontal cortex, an area
associated with cognitive processes such as focusing and attention.
Having ADHD as well as being dyslexic living with this learning disability
makes school extremely difficult. It is very hard for most people to understand
how someone with this problem lives every day. To me it is like an itch you can’t
scratch. Being on and off medication my whole life about 4 years ago I decided
to deal with this disorder without medication. Although very hard the side
effect aren’t as bad as when I was on the medication. I continue to live with
this every day some days are better than others but I hope that someday
neuroscientists can figure out a treatment and cause more specific to this
disorder. ADHD affects every sense of your body especially hearing and sight.
To me it seems that neuro transmitters are almost sparking. Hearing someone
talk next to me while listening to the teacher becomes almost impossible. In
this article about ADHD you will be able to learn more about this disorder as
well as the people that are trying to learn from it.

Perception

The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
